Need help with night vision goggles

[Hummer Guy]

I know that they have different generations. Also the type of tubes and where they're made are important to the image quality. I tried out a Gen 3+ unit that was about 2 grand, and it was cool, but not 2 grand cool -- still a little grainy at long range. Close range (20 ft or less) w/ the invisible light that came out was incredible, though.
